Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.626A>G (p.K209R) alteration is located in exon 10 (coding exon 9) of the TPTE2 gene. This alteration results from a A to G substitution at nucleotide position 626, causing the lysine (K) at amino acid position 209 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
